' and the like thread. In machines of this kind the threads coming from the thread former are wound on bobbins which haveto be replaced when they are full. This operation, hitherto effected by hand, besides the loss of time occasioned thereby, causes a stoppage of the'feed of the thread, dur ing which the thread formers often become clogged, necessitating a long and delicate cleaning operation.

The invention is for the purpose of auto matically replacing the full bobbins without causing stoppage of the drawing of the threads and without loss of material.

The annexed drawing illustrates an example of construction of the invention.

Figure 1 is a front elevation of so much of the machine as is necessary to illustrate the invention. Fig. 2 is a plan view of Fig. 1. Fig. 3' is a transverse section on line A-A of Fig. 1.

The bobbins 1, 1 for receiving the thread are mounted in pairs on double supports 2 which can turn around a horizontal shaft 3. They are provided with cheeks 11 and of a diameter sufficient to allow the bobbins to be covered with a thin layer of non-crossed parallel threads which facilitates the subsequent unwinding. These bobbins are mounted on their supports in such a way as to be easily detachable; springs 2, Fig. 3, maintain them in place.

The several supports 2 are connected together and with the pulley 4 by tie pieces 5, 5. Any convenient number of pairs of bobbins' can be connected together by the tie pieces, the pulley 4 is further connected to a sleeve 6 carrying a cam 7 and a disk 8 provided with two tappets 9, 9 diametrically opposite one another. The whole can rotate freely around the central shaft 3,

The shaft 3 driven by the pulley 10 is provided opposite the cheeks 11 of each pair of bobbins with friction rollers 12 which impart a movement of rotation to the bobbins shaft 21 and pinion 23 on said shaft 21 conforming with the speed at which the threads 13 are drawn. The threads are distributed on the surface of the bobbin by means of abar 14 provided with thread guides 14. The bar 14 has a screw threaded end 15 engaging a nut 16 formed by the hub of a toothed wheel 17, the rotation of which causes the bar 14 to move transversely in one direction or the other.

i The driving shaft 18 drives the central shaft 3 by the pulleys 19 and 10, and also the whole of the bobbins by the pulleys 20 and 4. The said shaft 18 also 0 erates the thread guide bar 14 by means of elt reversing gear comprising belt sheave 21*- fixed on shaft 18, lain and crossed, driving belts 21 and 21, ast and loose pulleys 20* and 21 mounted on shaft 21 pulley 21 on said shaft 21*, belt 22, pulley 21 mounted on which gears with toothed wheel 17. The reversing belt gear is actuated by means of the cam 7 which operates a lever 24 articulated to a draw bar 24 provided with belt shifting forks 9A". moved in one direction. by the cam 7 is moved in the opposite direction in any suitable manner as, for example, by means of the spring 24.

The apparatus operates as follows: The bobbins and the cam 7 are held by one of the tappets 9 which bears on a bar 25 slidable in guides 25, see Fig. 2. The bobbins 1 which are in front wind the threads 13 from right to left, while bobbins 1 rotate empty. hen the wlnding of the bobbins 1 is nearly completed the end 15 of the sliding bar 14 arriving at the end of its course to. the left operates by means of a tappet 26 on a lever 27 pivoted at 27 and the other end of which is articulated at 27 to the sliding bar. 25, the lever 27 thereby shifting the bar 25 toward the right. The bar 25 has a notch 28 which thereupon allows the tappet 9 to pass and allows the cam 7 and the bobbin frame to be rotated b means of the pulley 4; this rotation exten s for a semiturn, whereupon the tappet 9 in its turn abuts on the bar 25, the notch of which has moved to the right. During this semiturn the empty bobbins 1 without ceasing to rotate take the A place of the full bobbins 1 and the threads are wound thereon, the winding commencing this time from the left. During these movements the cam 7 having also made a The lever 24 which is 30 semiturn haschan ed the direction of movement of the thread guide bar 14, the guides 14; of which then conduct the threads from left to right. While the bobbins 1 are being wound, the full bobbins 1 are removed and replaced by empty ones. When the winding is nearly completed the tappet 26 meets the abutment 29 connected to the lever 27 the slide 25 is moved toward the left and allows the tappet 9 to pass and the above described movements are repeated in the reverse manner. v

The details of construction described above could be varied Without departing from the principle ofthe invention.

What I claim as my invention and desire to secure by Letters Patent of the United States is p 1. In a machine for manufacturing artificial silk and the like thread, the combination of a shaft, means for rotatin same, a pair of bobbins adapted to receive t e thread arranged diametrically opposite one another on each'side of said shaft, one of which is normally in position for winding the thread, a rotatable frame on which said bobbins are detachably mounted and having its axis of rotation coaxial with the axis of said shaft, means for impartin rotary movement to said bobbins by said shaft, a bar, a

- thread guide on said bar, means for imparting horizontal movement to said bar in two directions to guide the thread on to one or other of said bobbins, and means controlled by said bar, for periodically imparting a semi-rotation to said frame to bring the one or other of said bobbins into the normal position for winding the thread;

2. In a machine for manufacturing artificial silk and the like thread, the combination of a shaft, means for rotating same, a series of pairs of bobbins adapted to receive the thread, flanges on said bobbins, a series of rotatable frames having their axes .Of rotation coaxial with the axis of said shaft spring governed means carried b sai frames adaptedto detachably hold said bobbins thereon, tie pieces connecting said frames, disks mounted on said shaft engaging with said flanges of said bobbins and whereby the latter are rotated, a sleeve on said shaft, a pulley on said sleeve connected to one of said frames, means for imparting rotation to said pulley and said frames, means for automatically reversing said rotation, means for limiting said rotation to a semiturn in either direction, to bring one or other of the bobbins of the series of pairs into position for winding the threads, a bar, thread guides thereon, and means for automatically impartingreciprocating horizontal movement to sald bar to guide the threads on to the bobbins in operation.

In witness whereof I have signed this specification in the presence of two witnesses.
